Previously developed techniques for generating hydrogen from ethanol are best suited to large - scale production at specialized facilities, however, because they require external sources of heat.
The Obama administration seems to agree, granting $ 786 million in 2009 for biofuels research and setting up the Biofuels Interagency Working Group to study how best to meet the renewable fuel standard mandated by Congress that will require increasing the amount of renewable fuels, such as ethanol, to 36 billion gallons by 2022.
By applying this new technology to enzymes required for the production of ethanol — an important biofuel — the researchers were able to increase alcohol production by over 200 %.
Would an engine designed for 100 % ethanol require a catalytic converter?
Since 2010, under the requirements of the bipartisan Energy Independence and Security Act of 2007, the EPA has been required to include a standard for cellulosic ethanol.
David Pimentel, a professor of ecology at Cornell University who has been studying grain alcohol for 20 years, and Tad Patzek, an engineering professor at the University of California, Berkeley, co-wrote a recent report that estimates that making ethanol from corn requires 29 percent more fossil energy than the ethanol fuel itself actually contains.
In the case of sugarcane ethanol, a lot of energy inputs are required, especially for purifying the ethanol, but those inputs are being satisfied by burning the sugarcane ethanol residues to produce process heat.
I have previously weighed in on the current status of cellulosic ethanol technology, as well as the amount of biomass required for implementation.
The other concern is the high degree of embedded (and unsustainable) fossil fuels required for grain ethanol production.
From 2007 to 2013, corn ethanol interests spent $ 158 million lobbying for more mandates and subsidies — and $ 6 million in campaign contributions — for a fuel that reduces mileage, damages engines, requires enormous amounts of land, water and fertilizer, and from stalk to tailpipe emits more carbon dioxide than gasoline.
We are concerned with America's growing ethanol industry, the implications it has in setting a precedent for additional biomass based energy, and the massive agricultural industrialization of the world's remaining rainforests and other natural wildlands this would require.
Because so little energy is required to cultivate crops such as switchgrass for cellulosic ethanol production, and because electricity can be co-produced using the residues of such cellulosic fuel production, reductions in greenhouse gas emissions for celluslosic ethanol when compared to gasoline are greater than 100 per cent.
Coupled with our recently - announced off - take agreement with Tenaska BioFuels, LLC, the key input and output contracts required for financing are now resolved,» stated Arnold Klann, CEO of BlueFire Renewables, Inc. «This is a very exciting time for BlueFire Renewables as we complete the final steps to bringing cellulosic ethanol to fruition in the U.S. marketplace.»
Qteros has developed a proprietary technology «C3» (Complete Cellulosic Conversion), which is uniquely capable of producing cellulosic ethanol in one step, thus reducing the costs and capital required for making biofuels.
As biofuel mandates increase, the ethanol volume required for blending into gasoline will exceed 10 percent — known as the «E10 Blend Wall.»
We've been talking about flaws in the RFS for some time, and the chorus of voices has grown because requiring increasing volumes of ethanol in the nation's fuel supply could affect vehicle owners, consumers paying for fuel and food, the environment and the global food supply.
[3] Helioculture allows for brackish water or graywater, nonindustrial waste water from sources such as baths and washing machines, [4] to be used, while traditional biofuels such as cellulosic ethanol require fresh water.
However, if imports of sugarcane ethanol require that Americans purchase additional ethanol relative to a baseline with the tariff, then an argument could be made for keeping the tariff.
The findings have significant implications for E.U. biofuels policy, which requires biodiesel and ethanol to offer emissions savings relative to conventional fossil fuels.
Unfortunately, the Environmental Protection Agency did just that last week, setting new quotas for 2012 that will require the nation's refiners to add 8.65 million gallons of cellulosic ethanol to America's fuel supplies.
At issue is whether to suspend a five - year - old federal mandate requiring more ethanol in gasoline each year, a policy that has diverted almost half of the domestic corn supply from animal feedlots to ethanol refineries, driven up corn prices and plantings and created a desperate competition for corn as drought grips the nation's farm belt.
Brian Dodge, just for comparison and context, converting all gasoline using vehicles to 100 % corn - based ethanol would require almost 7x the current acreage in corn, and 30 % more than the current total cropland of the US.
Because the wind turbines would require a modest amount of spacing between them to allow room for the blades to spin, wind farms would occupy about 0.5 percent of all U.S. land, but this amount is more than 30 times less than that required for growing corn or grasses for ethanol.
Corn used for ethanol unfortunately competes with a staple foodstuff, and requires significant amounts of land area.
If you divide 154 mmt (corn for ethanol) / 321 mmt (total grain harvest) = corn for ethanol might require 48 percent of the US grain harvest (corn and wheat combined).
What we would like to see from Toyota and other car makers: More affordable very fuel - efficient and low - emission hybrids, plug - in hybrids, all cars flex fuel so that they can run on cellulosic ethanol when it is available (the fuel sensors required for that are apparently only about $ 30 - no reason not to include them in all cars), diesel - hybrids with the latest emission technology (to run on biodiesel where available, of course) and, as soon as battery technology is ready, affordable electric - only vehicles.
When EPA green - lighted E15 use, it knew E15 vehicle testing was ongoing but decided not to wait for the results — most likely to raise the permissible concentration level of ethanol in fuels so that greater volumes could be used, as required by the Renewable Fuel Standard (RFS).
